> An Unsafe-based ArrayData implementation. To begin with, we can encode data
> this way:
> first 4 bytes is the # elements
> then each 4 byte is the start offset of the element, unless it is negative,
> in which case the element is null.
> followed by the elements themselves
> For example, [10, 11, 12, 13, null, 14], internally should be represented as
> (each 4 bytes)
> 5, 28, 32, 36, 40, -44, 48, 10, 11, 12, 13, 0, 14
